BACKGROUND

A number of diseases are associated with aberrant expression of a gene product (e.g., an RNA transcript or protein) of a gene. The resulting aberrant amounts of RNA transcripts may lead to disease due to corresponding changes in protein expression. Changes in the amount of a particular RNA transcript may be the result of several factors. First, changes in the amount of RNA transcripts may be due to an aberrant level of transcription of a particular gene, such as by the perturbation of a transcription factor or a portion of the transcription process, resulting in a change in the expression level of a particular RNA transcript. Second, changes in the splicing of particular RNA transcripts, such as by perturbation of a particular splicing process or mutations in the gene that lead to modified splicing can change the levels of a particular RNA transcript. Changes to the stability of a particular RNA transcript or to components that maintain RNA transcript stability, such as the process of poly-A tail incorporation or an effect on certain factors or proteins that bind to and stabilize RNA transcripts, may lead to changes in the levels of a particular RNA transcript. Also, the level of translation of particular RNA transcripts can affect the amount of those transcripts, affecting or upregulating RNA transcript decay processes. Finally, aberrant RNA transport or RNA sequestration may also lead to changes in functional levels of RNA transcripts, and may have an effect on the stability, further processing, or translation of the RNA transcripts.

Often, diseases associated with changes to RNA transcript amount are treated with a focus on the aberrant protein expression. However, if the processes responsible for the aberrant changes in RNA levels, such as components of the splicing process or associated transcription factors or associated stability factors, could be targeted by treatment with a small molecule, it would be possible to restore protein expression levels such that the unwanted effects of the expression of aberrant levels of RNA transcripts or associated proteins. Therefore, there is a need for methods of modulating the amount of RNA transcripts encoded by certain genes as a way to prevent or treat diseases associated with aberrant expression of the RNA transcripts or associated proteins.

SUMMARY

In one aspect, provided herein is a recognition element for splicing modifier (otherwise referred to as “REMS”) that plays a role in the recognition of a compound described herein. In a specific embodiment, the REMS has the nucleotide sequence GAgurngn at the RNA level, wherein r is A or G (i.e., a purine nucleotide) and n is any nucleotide. In another specific embodiment, the REMS has the nucleotide sequence GAguragu at the RNA level, wherein r is A or G. In another specific embodiment, the REMS has the nucleotide sequence ANGAgurngn at the RNA level, wherein r is A or G (i.e., a purine nucleotide) and n or N is any nucleotide. In a preferred embodiment, the REMS has the nucleotide sequence ANGAguragu at the RNA level, wherein r is A or G and N is any nucleotide. In a specific embodiment, the REMS is located in the 5′ splice site. In certain embodiments, the REMS is located within an exon, such as in FoxM1 exon 7a. Without being bound by any theory or mechanism, it is believed that compounds described herein increase the affinity of the interaction between U1 snRNP and the nucleotides ANGA of the REMS. This belief is based, in part, on the recognition that REMS comprises the U1 snRNP binding site.

In FIG. 1D, the REMS is located in the 5′ splice site of a precursor RNA (e.g., precursor mRNA). In the presence of a compound described herein, the nucleotides between the REMS in the 5′ splice site and a downstream 3′ splice site of a precursor RNA (except the nucleotides of the exon) are removed and the exons of the precursor RNA are spliced together. In FIG. 1B, the REMS is located within an exon in a precursor RNA. In the presence of a compound described herein, the nucleotides between the REMS and a downstream 3′ splice site of a precursor RNA (except nucleotides GA or ANGA of REMS) are removed and the remaining portions of the precursor RNA are spliced together, which may result in an RNA transcript with a truncated open reading frame due to a frameshift or internal deletions within the open reading frame.

DETAILED DESCRIPTION Recognition Element for Splicing Modifier (REMS)

In one aspect, provided herein is a recognition element for splicing modifier (otherwise referred to as “REMS”) that plays a role in the recognition of a compound described herein. In a specific embodiment, the REMS has the nucleotide sequence GAgurngn at the RNA level, wherein r is A or G (i.e., a purine nucleotide) and n is any nucleotide. In another specific embodiment, the REMS has the nucleotide sequence GAguragu at the RNA level, wherein r is A or G. In another specific embodiment, the REMS has the nucleotide sequence ANGAgurngn at the RNA level, wherein r is A or G (i.e., a purine nucleotide) and n or N is any nucleotide. In a preferred embodiment, the REMS has the nucleotide sequence ANGAguragu at the RNA level, wherein r is A or G and N is any nucleotide.

In the context of DNA, in a specific embodiment, the nucleotide sequence encoding a REMS has the sequence GAgtrngn, wherein r is A or G (i.e., a purine nucleotide) and n is any nucleotide. In another specific embodiment, in the context of DNA, the nucleotide sequence encoding a REMS has the sequence GAgtragt, wherein r is A or G. In a specific embodiment, in the context of DNA, the nucleotide sequence encoding a REMS has the sequence ANGAgtrngn, wherein r is A or G (i.e., a purine nucleotide) and n or N is any nucleotide. In a preferred embodiment, in the context of DNA, the nucleotide sequence encoding a REMS has the sequence ANGAgtragt, wherein r is A or G and N is any nucleotide.

A REMS can be part of an endogenous RNA or can be introduced into an RNA sequence that does not naturally contain the REMS sequence (in which case, the introduced REMS is a non-endogenous REMS, i.e., a REMS not naturally present in the corresponding RNA. A nucleotide sequence encoding REMS can also be part of an endogenous DNA sequence, or a nucleotide sequence encoding a REMS can be introduced into a DNA sequence that does not naturally contain the nucleotide sequence encoding the REMS introduced.

In a specific embodiment, the REMS is located in the 5′ splice site. In certain embodiments, the REMS is located within an exon, such as in FoxM1 exon 7a. Without being bound by any theory or mechanism, it is believed that compounds described herein increase the affinity of the interaction between U1 snRNP and the nucleotides ANGA of the REMS. This belief is based, in part, on the recognition that REMS comprises the U1 snRNP binding site.

In FIG. 1D, the REMS is located in the 5′ splice site of a precursor RNA. In the presence of a compound described herein, the nucleotides between the REMS in the 5′ splice site and 3′ splice site of a precursor RNA are (except the nucleotides of the exon) removed and the exons of the precursor RNA are spliced together. In FIG. 1B, the REMS is located within an exon in a precursor RNA. In the presence of a compound described herein, the nucleotides between the REMS and the 3′ splice site of a precursor RNA (except the nucleotides GA or ANGA) are removed and the remaining portions of the precursor RNA are spliced together, which may result in an RNA transcript with a truncated open reading frame or internal deletions within the open reading frame.

In one embodiment, a precursor RNA transcript comprises three exons and two introns, wherein a REMS is present endogenously or introduced into the 5′ splice site of the exon 2-intron 2 boundary of the RNA transcript. In the absence of a compound described herein, some degree of exon 2 skipping will occur and two mRNAs will be produced, e1e2e3 and e1e3. When compound is added, the balance between the two mRNAs produced is shifted so that more e1e2e3 and less e1e3 mRNA is produced. See FIG. 1.

In another embodiment, a precursor RNA transcript comprises two exons and one intron, wherein a REMS is present endogenously or introduced into the 5′splice site of the exon 1—intron 1 boundary of the RNA transcript. In the absence of a compound described herein, some degree of inhibition of splicing altogether will occur and two RNA products will be produced—pre-mRNA e1i1e2, which is usually unstable and degraded and, thus, usually not translated so no functional protein is produced, and e1e2 mRNA. When compound is added, the balance between the two RNA products is shifted so that more e1e2 and less e1i1e2 is produced. See FIG. 1.

In another embodiment, a precursor RNA transcript comprises a REMS inside an exon (e.g., FOXM1 exon 7a). In this situation, in the absence of a compound described herein, the splicing outcome is driven by the distal 5′ splice site and the 5′splice site mediates whole exon splicing. However, when a compound described herein is present, splicing at the REMS is induced and inclusion of a shorter exon results. See FIG. 1B.

When a REMS is introduced into an RNA sequence, the splicing outcome will be governed by the presence/absence of an upstream 5′ splice site(s), upstream 3′ splice sites, and downstream 3′ splice site(s). See FIGS. 1A and 1C.

When a REMS is introduced into an RNA sequence, the splicing outcome will be governed by the presence/absence of an upstream 5′ splice site(s), upstream 3′ splice sites, and downstream 3′ splice site(s) and endogenous splicing control sequences.

As used herein, the term “protected” means that a functional group on a compound of Formula (I) is in a form modified to preclude undesired side reactions at the protected site when the compound is subjected to a reaction. Suitable protecting groups will be recognized by those with ordinary skill in the art as well as by reference to standard textbooks such as, for example, T. W. Greene et al, Protective Groups in Organic Synthesis (1991), Wiley, New York.

Prodrugs of a compound of Formula (I) or a form thereof are also contemplated herein.

As used herein, the term “prodrug” means that a functional group on a compound of Formula (I) is in a form (e.g., acting as an active or inactive drug precursor) that is transformed in vivo to yield an active or more active compound of Formula (I) or a form thereof. The transformation may occur by various mechanisms (e.g., by metabolic and/or non-metabolic chemical processes), such as, for example, by hydrolysis and/or metabolism in blood, liver and/or other organs and tissues. A discussion of the use of prodrugs is provided by V. J. Stella, et. al., “Biotechnology: Pharmaceutical Aspects, Prodrugs: Challenges and Rewards,” American Association of Pharmaceutical Scientists and Springer Press, 2007.

In one example, when a compound of Formula (I) or a form thereof contains a carboxylic acid functional group, a prodrug can comprise an ester formed by the replacement of the hydrogen atom of the acid group with a functional group such as alkyl and the like. In another example, when a compound of Formula (I) or a form thereof contains an alcohol functional group, a prodrug can be formed by the replacement of the hydrogen atom of the alcohol group with a functional group such as alkyl or substituted carbonyl and the like. In another example, when a compound of Formula (I) or a form thereof contains an amine functional group, a prodrug can be formed by the replacement of one or more amine hydrogen atoms with a functional group such as alkyl or substituted carbonyl. In another example, when a compound of Formula (I) or a form thereof contains a hydrogen substituent, a prodrug can be formed by the replacement of one or more hydrogen atoms with an alkyl substituent.

Pharmaceutically acceptable prodrugs of compounds of Formula (I) or a form thereof include those compounds substituted with one or more of the following groups: carboxylic acid esters, sulfonate esters, amino acid esters phosphonate esters, mono-, di- or triphosphate esters or alkyl substituents where appropriate. As described herein, it is understood by a person of ordinary skill in the art that one or more of such substituents may be used to provide a compound of Formula (I) or a form thereof for use as a prodrug.

The compounds of Formula (I) can form salts which are intended to be included within the scope of this description. Reference to a compound of Formula (I) herein is understood to include reference to salts thereof, unless otherwise indicated. The term “salt(s)”, as employed herein, denotes acidic salts formed with inorganic and/or organic acids, as well as basic salts formed with inorganic and/or organic bases. In addition, when a compound of Formula (I) contains both a basic moiety, such as, but not limited to a pyridine or imidazole, and an acidic moiety, such as, but not limited to a carboxylic acid, zwitterions (“inner salts”) may be formed and are included within the term “salt(s)” as used herein.

The term “pharmaceutically acceptable salt(s)”, as used herein, means those salts of compounds described herein that are safe and effective (i.e., non-toxic, physiologically acceptable) for use in mammals and that possess biological activity, although other salts are also useful. Salts of the compounds of Formula (I) may be formed, for example, by reacting a compound of Formula (I) with an amount of acid or base, such as an equivalent or stoichiometric amount, in a medium such as one in which the salt precipitates or in an aqueous medium followed by lyophilization.

Pharmaceutically acceptable salts include one or more salts of acidic or basic groups present in compounds described herein. Embodiments of acid addition salts include, and are not limited to, acetate, acid phosphate, ascorbate, benzoate, benzenesulfonate, bisulfate, bitartrate, borate, butyrate, chloride, citrate, camphorate, camphorsulfonate, ethanesulfonate, formate, fumarate, gentisinate, gluconate, glucaronate, glutamate, hydrobromide, hydrochloride, dihydrochloride, hydroiodide, isonicotinate, lactate, maleate, methanesulfonate, naphthalenesulfonate, nitrate, oxalate, pamoate, pantothenate, phosphate, propionate, saccharate, salicylate, succinate, sulfate, tartrate, thiocyanate, toluenesulfonate (also known as tosylate), trifluoroacetate salts and the like.

More particular embodiments include a chloride, hydrochloride, dihydrochloride, hydrobromide or trifluoroacetate salt.

Additionally, acids which are generally considered suitable for the formation of pharmaceutically useful salts from basic pharmaceutical compounds are discussed, for example, by P. Stahl et al, Camille G. (eds.) Handbook of Pharmaceutical Salts. Properties, Selection and Use. (2002) Zurich: Wiley-VCH; S. Berge et al, Journal of Pharmaceutical Sciences (1977) 66(1) 1-19; P. Gould, International J. of Pharmaceutics (1986) 33, 201-217; Anderson et al, The Practice of Medicinal Chemistry (1996), Academic Press, New York; and in The Orange Book (see, website for Food & Drug Administration, Washington, D.C.). These disclosures are incorporated herein by reference thereto.

Suitable basic salts include, but are not limited to, aluminum, ammonium, calcium, lithium, magnesium, potassium, sodium, zinc, and diethanolamine salts. Certain compounds described herein can also form pharmaceutically acceptable salts with organic bases (for example, organic amines) such as, but not limited to, dicyclohexylamines, tert-butyl amines and the like, and with various amino acids such as, but not limited to, arginine, lysine and the like. Basic nitrogen-containing groups may be quarternized with agents such as lower alkyl halides (e.g., methyl, ethyl, and butyl chlorides, bromides and iodides), dialkyl sulfates (e.g., dimethyl, diethyl, and dibutyl sulfates), long chain halides (e.g., decyl, lauryl, and stearyl chlorides, bromides and iodides), aralkyl halides (e.g., benzyl and phenethyl bromides), and others.

All such acid salts and base salts are intended to be pharmaceutically acceptable salts within the scope of the description herein and all such acid and base salts are considered equivalent to the free forms of the corresponding compounds for the purposes described herein.

Compounds of Formula I and forms thereof may further exist in a tautomeric form. All such tautomeric forms are contemplated herein as part of the present description.

The compounds of Formula (I) may contain asymmetric or chiral centers, and, therefore, may exist in different stereoisomeric forms. The present description is intended to include all stereoisomeric forms of the compounds of Formula (I) as well as mixtures thereof, including racemic mixtures.

The compounds of Formula (I) described herein may include one or more chiral centers, and as such may exist as racemic mixtures (R/S) or as substantially pure enantiomers and diastereomers. The compounds may also exist as substantially pure (R) or (S) enantiomers (when one chiral center is present). In one embodiment, the compounds of Formula (I) described herein are (S) isomers and may exist as enantiomerically pure compositions substantially comprising only the (S) isomer. In another embodiment, the compounds of Formula (I) described herein are (R) isomers and may exist as enantiomerically pure compositions substantially comprising only the (R) isomer. As one of skill in the art will recognize, when more than one chiral center is present, the compounds of Formula (I) described herein may also include portions described as an (R,R), (R,S), (S,R) or (S,S) isomer, as defined by IUPAC Nomenclature Recommendations.

As used herein, the term “substantially pure” refers to compounds consisting substantially of a single isomer in an amount greater than or equal to 90%, in an amount greater than or equal to 92%, in an amount greater than or equal to 95%, in an amount greater than or equal to 98%, in an amount greater than or equal to 99%, or in an amount equal to 100% of the single isomer.

In one aspect, a compound of Formula (I) is a substantially pure (S) enantiomer present in an amount greater than or equal to 90%, in an amount greater than or equal to 92%, in an amount greater than or equal to 95%, in an amount greater than or equal to 98%, in an amount greater than or equal to 99%, or in an amount equal to 100%.

In one aspect, a compound of Formula (I) is a substantially pure (R) enantiomer present in an amount greater than or equal to 90%, in an amount greater than or equal to 92%, in an amount greater than or equal to 95%, in an amount greater than or equal to 98%, in an amount greater than or equal to 99%, or in an amount equal to 100%.

As used herein, a “racemate” is any mixture of isometric forms that are not “enantiomerically pure”, including mixtures such as, without limitation, in a ratio of about 50/50, about 60/40, about 70/30, about 80/20, about 85/15 or about 90/10.

In addition, the present description embraces all geometric and positional isomers. For example, if a compound of Formula (I) incorporates a double bond or a fused ring, both the cis- and trans-forms, as well as mixtures, are embraced within the scope of the description herein.

Diastereomeric mixtures can be separated into their individual diastereomers on the basis of their physical chemical differences by methods well known to those skilled in the art, such as, for example, by chromatography and/or fractional crystallization. Enantiomers can be separated by use of chiral HPLC column or other chromatographic methods known to those skilled in the art.

Enantiomers can also be separated by converting the enantiomeric mixture into a diastereomeric mixture by reaction with an appropriate optically active compound (e.g., chiral auxiliary such as a chiral alcohol or Mosher's acid chloride), separating the diastereomers and converting (e.g., hydrolyzing) the individual diastereomers to the corresponding pure enantiomers. Also, some of the compounds of Formula (I) may be atropisomers (e.g., substituted biaryls) and are considered part of this description.

All stereoisomer forms (for example, geometric isomers, optical isomers, positional isomers and the like) of the present compounds (including salts, solvates, esters and prodrugs and transformed prodrugs thereof) which may exist due to asymmetric carbons on various substituents, including enantiomeric forms (which may exist even in the absence of asymmetric carbons), rotameric forms, atropisomers, diastereomeric forms and regioisomeric forms are contemplated within the scope of the description herein. For example, if a compound of Formula (I) incorporates a double bond or a fused ring, both the cis- and trans-forms, as well as mixtures thereof, are embraced within the scope of the description herein. Also, for example, all keto-enol and imine-enamine tautomeric forms of the compounds are included in the description herein. Individual stereoisomers of the compounds of Formula (I) described herein may, for example, be substantially free of other isomers, or may be present in a racemic mixture, as described supra.

The use of the terms “salt,” “prodrug” and “transformed prodrug” are intended to equally apply to the salts, prodrugs and transformed prodrugs of all contemplated isotopologues, stereoisomers, racemates or tautomers of the instant compounds.

The term “isotopologue” refers to isotopically-enriched compounds which are identical to those recited herein, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into compounds described herein include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine and chlorine, such as H², H³, C¹³, C¹⁴, N¹⁵, O¹⁸, O¹⁷, P³¹, P³², S³⁵, F¹⁸, Cl³⁵ and Cl³⁶, respectively, each of which is also within the scope of this description.

Certain isotopically-enriched compounds described herein (e.g., those labeled with H³ and C¹⁴) are useful in compound and/or substrate tissue distribution assays. Tritiated (i.e., H³) and carbon-14 (i.e., C¹⁴) isotopes are particularly preferred for their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium (i.e., “deuterium enriched”) may afford certain therapeutic advantages resulting from greater metabolic stability (e.g., increased in vivo half-life or reduced dosage requirements) and hence may be preferred in some circumstances. Isotopically-enriched compounds of Formula (I) can generally be prepared using procedures known to persons of ordinary skill in the art by substituting an appropriate isotopically-enriched reagent for a non-isotopically-enriched reagent.

When the compounds are enriched with deuterium, the deuterium-to-hydrogen ratio on the deuterated atoms of the molecule substantially exceeds the naturally occurring deuterium-to-hydrogen ratio.

An embodiment described herein may include an isotopologue form of the compound of Formula (I), wherein the isotopologue is substituted on one or more atom members of the compound of Formula (I) with one or more deuterium atoms in place of one or more hydrogen atoms.

An embodiment described herein may include a compound of Formula (I) and forms thereof, wherein a carbon atom may have from 1 to 3 hydrogen atoms optionally replaced with deuterium.

One or more compounds described herein may exist in unsolvated as well as solvated forms with pharmaceutically acceptable solvents such as water, ethanol, and the like, and the description herein is intended to embrace both solvated and unsolvated forms.

As used herein, the term “solvate” means a physical association of a compound described herein with one or more solvent molecules. This physical association involves varying degrees of ionic and covalent bonding, including hydrogen bonding. In certain instances the solvate will be capable of isolation, for example when one or more solvent molecules are incorporated in the crystal lattice of the crystalline solid. As used herein, “solvate” encompasses both solution-phase and isolatable solvates. Non-limiting examples of suitable solvates include ethanolates, methanolates, and the like.

One or more compounds described herein may optionally be converted to a solvate. Preparation of solvates is generally known.

In some embodiments the artificial gene construct is an RNA molecule modified to enable cellular uptake. In certain embodiments, the artificial gene construct is an RNA molecule containing pseudouridine or other modified/artificial nucleotides for enhanced cellular uptake and gene expression.

The use of an artificial gene construct described herein in gene therapy allows one to regulate the amount of a functional protein produced from the construct depending on whether or not a compound described herein is present. The compound is essentially a tunable switch that, depending on the amount and duration of the dose of the compound, regulates the amount of functional protein produced.

In certain embodiments, an RNA transcript transcribed from an artificial gene construct that is DNA would not produce or produce substantially less functional protein in the absence of a compound described herein than the amount of functional protein produced in the presence of a compound described herein. For example, if the artificial gene construct comprises a nucleotide sequence encoding a REMS in a 5′ splice site, which is upstream of a nucleotide sequence encoding a 3′ splice site, then less splicing would occur in the absence of the compound and this would result in exon skipping which would ultimately result in less functional protein being produced. In a particular example, if there is an IGF1 precursor mRNA containing a REMS-controlled exon, then in the absence of a compound described herein an exon-skipped mRNA is produced which cannot be translated into full length, functional IGF1. However, in the presence of a compound described herein, a full length, functional IGF1 protein is produced. Alternatively, in certain embodiments, an RNA transcript transcribed from an artificial gene construct that is DNA would not produce or would produce substantially less functional protein in the presence of a compound described herein than the amount of functional protein produced in the absence of a compound described herein. For example, if the artificial gene construct comprises a nucleotide sequence encoding a REMS in the middle of an exon, then ectopic splicing would occur in the presence of a compound described herein and this would result in reduction in the production of the functional protein. However, in the absence of a compound described herein, the normal splicing would occur, and the production of the functional protein will not be reduced. Either way, the amount of the functional protein produced can be titrated based on amount of a compound used and duration of exposure to the compound.

In certain embodiments, an artificial gene construct or vector comprising an artificial gene construct is used in cell culture. For example, in a cell(s) transfected with an artificial gene construct or transduced with a vector comprising an artificial gene construct, the amount of a functional protein produced from the artificial gene construct can be altered depending upon whether or not a compound described herein is contacted with the transfected cell(s). For example, if the artificial gene construct comprises a nucleotide sequence encoding a REMS in a 5′ splice site, which is upstream of a nucleotide sequence encoding a 3′ splice site, then less splicing would occur in the absence of the compound and this would result in exon skipping which would ultimately result in less functional protein being produced. Thus, the use of an artificial gene construct described herein allows one to regulate the amount of a functional protein produced from the construct depending on whether or not a compound described herein is present. In other words, a compound described herein is essentially a switch that regulates the amount of functional protein produced. This regulation of the production of functional protein could be useful, e.g., when trying to assess the role of certain genes or the effects of certain agents on pathways. The amount of the functional protein produced can be modified based on the amount of a compound described herein that is contacted with the transfected cell and/or how long the compound is contacted with the transfected cell.

In certain embodiments, an animal (e.g., a non-human animal, such as a mouse, rat, fly, etc.) is engineered to contain an artificial gene construct or a vector comprising an artificial gene construct. Techniques known to one of skill in the art may be used to engineer such animals. The amount of functional protein produced by this engineered animal can be regulated by whether or not a compound described herein is administered to the animal. The amount of the functional protein produced can be titrated based on the dose and/or the duration of administration of a compound described herein to the engineered animal. In certain embodiments, the artificial gene construct encodes a detectable reporter gene, such as green fluorescent protein (GFP), yellow fluorescent protein (YFP), red fluorescent protein, beta galactosidase, renilla luciferase, firefly luciferase, etc. In accordance with this embodiment, the engineered animal may be used to monitor development at different stages, visualize tissue function, etc. In other embodiments, the artificial gene construct encodes a therapeutic gene product, such as described the gene product of a gene in Tables 1-4 and 6, or one of the following genes: SMN2, RIG-I, MDA5, LGP2, TLR7, TLR9, interferon gamma, vascular endothelial growth factor (VEGF), HER2, PSK9, Insulin receptor, CHM, growth hormone, IGF1, utrophin (UTRN), or EPO. In accordance with this embodiment, the engineered animal may be used to monitor development at different stages or in functional biological studies where a certain protein or protein isoform needs to be expressed only for a period of time and not constitutively, etc.

In certain embodiments, an artificial gene construct or a vector comprising an artificial gene construct are used in gene therapy.

Gene Therapy

In another aspect, provided herein are artificial gene constructs or vectors comprising an artificial gene construct for use in gene therapy. The use of an artificial gene construct described herein in gene therapy allows one to regulate the amount of a functional protein produced from the construct depending on whether or not a compound described herein is present. The compound is essentially a switch that regulates the amount of functional protein produced.

In certain embodiments, an RNA transcript transcribed from an artificial gene construct that is DNA would not produce or produce substantially less functional protein in the absence of a compound described herein than the amount of functional protein produced in the presence of a compound described herein. For example, if the artificial gene construct comprises a nucleotide sequence encoding a REMS in a 5′ splice site, which is upstream of a nucleotide sequence encoding a 3′ splice site, then less splicing would occur in the absence of the compound and this would result in exon skipping which would ultimately result in less functional protein being produced. In a particular example, if there is an IGF1 precursor mRNA containing a REMS-controlled exon, then in the absence of a compound described herein an exon-skipped mRNA is produced which cannot be translated into full length, functional IGF1. However, in the presence of a compound described herein, a full length, functional IGF1 protein is produced. The amount of the functional protein produced can be titrated based on dose and duration of dosing of the compound. In this example, the IGF1 protein is turned on and off depending upon whether the compound is present, which may be beneficial for a subject to maintain muscle health. Thus, the use of an artificial gene construct or a vector comprising an artificial gene construct is useful may be useful in treating and/or preventing certain conditions or diseases associated with genes, such as those genes described in Tables 1-4 and 5, or the one of the following genes: SMN2, RIG-I, TLR7, TLR9, interferon gamma, vascular endothelial growth factor (VEGF), CHM, growth hormone, IGF1, or EPO. The conditions or diseases may include those described herein. Alternatively, in certain embodiments, an RNA transcript transcribed from an artificial gene construct that is DNA would not produce or would produce substantially less functional protein in the presence of a compound described herein than the amount of functional protein produced in the absence of a compound described herein. For example, if the artificial gene construct comprises a nucleotide sequence encoding a REMS in the middle of an exon, then ectopic splicing would occur in the presence of a compound described herein and this would result in reduction in the production of the functional protein. However, in the absence of a compound described herein, the normal splicing would occur, and the production of the functional protein will not be reduced. The amount of the functional protein produced can be titrated based on dose and duration of dosing of the compound.

An artificial gene construct, a vector comprising the artificial gene construct, or an RNA molecule comprising an artificial gene construct modified to enable cellular uptake may be introduced into cells or administered directly to patients. In one embodiment, an artificial gene construct or a vector comprising the artificial gene construct is introduced into cells ex vivo or in vivo. In a specific embodiment, an artificial gene construct or vector is introduced into a cell(s) ex vivo and the cell(s) may be administered to a subject. Various techniques known to one of skill in the art may be used to introduce an artificial gene construct or vector comprising the artificial gene construct into a cell(s), such as electroporation, transfection, transformation, etc. In another embodiment, an artificial gene construct or vector comprising the artificial gene construct is administered to a subject. The artificial gene construct or vector comprising the artificial gene construct may be administered to a subject by any technique known to one skilled in the art, e.g., intramuscularly, intravenously, subcutaneously, intradermally, topically, intrathecally, intraperitoneally, intratumorally, etc. In some embodiments, the artificial gene construct or vector comprising the artificial gene construct is administered to a subject systemically. In other embodiments, the artificial gene construct or vector comprising the artificial gene construct is administered to a subject locally.

Altering Endogenous Genes

In another aspect, provided herein are method for altering an endogenous gene such that it contains a nucleotide sequence encoding a REMS, or contains an additional nucleotide sequence encoding a REMS (in other words, a REMS not naturally found in the endogenous gene, i.e., a non-endogenous REMS). Techniques known to one of skill in the art can be used to introduce a REMS into an endogenous gene, e.g., the CRISPR-Cas approach, TALEN, or ZFN may be used. In certain embodiments, a nucleotide sequence encoding an existing 5′ splice site can be replaced with a REMS or a REMS may be inserted internally within an exon. In introducing a nucleotide sequence encoding a REMS into an endogenous gene, care should be taken so as not to disrupt an open reading frame or introduce a stop codon. The introduction of a nucleotide sequence encoding a REMS into an endogenous gene may or may not result in an amino acid change at the protein level. In certain embodiments, the introduction of a nucleotide sequence encoding a REMS into an endogenous gene results in an amino acid change at the protein level. In some embodiments, this amino acid change is a conservative amino acid substitution. In other embodiments, the introduction of a nucleotide sequence encoding a REMS into an endogenous gene does not result in an amino acid change at the protein level.

Kits

In one aspect, provided herein are kits comprising, in a container, an artificial gene construct or a vector comprising an artificial construct. In certain embodiments, the kits further comprise a compound described herein, in a separate container, and/or a negative control, such as phosphate buffered saline or a compound that does not recognize REMS, in a separate container. In some embodiments, the kits further comprise primers and/or antibodies, in one or more separate containers, for assessing the production of an mRNA transcript from an artificial gene construct and/or protein production therefrom.

In another aspect, provided herein are kits comprising, in one or more containers, the components and/or reagents necessary to produce an artificial gene construct and/or a vector comprising an artificial gene construct. In another aspect, provided herein are kits comprising, in one or more containers, the components and/or reagents necessary to alter an endogenous gene so that it contains a nucleotide sequence encoding a REMS or an additional nucleotide sequence encoding a REMS (in other words, a REMS not naturally found in the endogenous gene, i.e., a non-endogenous REMS).

Such variations of the present description that may be now known or later developed, which would be within the purview of one skilled in the art to ascertain, are considered to fall within the scope of the present description and as hereinafter claimed. The example below illustrates the existence of a recognition element for splicing modifier (REMS) that is important for the recognition of a compound described herein, and the binding of such a compound to the REMS on a precursor RNA permits or enhances the splicing of the precursor RNA, and suggests the usefulness of the REMS in combination with a compound described herein for modulating RNA splicing, and for modulating the amount of a gene product.

Materials and Methods

Minigene Constructs, Mutagenesis, Transfection, and End-Point RT-PCR Analysis

The SMN2 minigene construct was prepared by PCR amplification of DNA corresponding to a region of the SMN2 gene starting from the 5′ end of exon 6 and ending at nucleotide 23 of exon 8 using specific primers (Forward: 5′-CGCGGATCCATAATTCCCCCACCACCTC-3′, reverse 5′-CGCGGATCCGTGCTGCTCTATGCCAGCA-3′). The PCR fragment was cloned into the BamHI site of a derivative of the original pcDNA 3.1/Hygro vector which was modified as disclosed in United States Patent Publication US2005/0048549. Nucleotide alterations were introduced by site-directed mutagenesis using the GeneArt site-directed mutagenesis system (Life Technologies, Inc.). All mutants of SMN1 and SMN2 in this Example were derived from the SMN2 minigene by a single nucleotide or double nucleotide substitution in exon 7 or intron 7. See Naryshkin et al., Science (2014) 345: 688-93, which is incorporated herein by reference, for a description of the SMN2 minigene.

For plasmid transfections, 15 ng of plasmid DNA were transfected in SMA type 1 patient fibroblasts GM03813 in 96-well plates. Transfections were carried out using Lipofectamine LTX (Life Technologies, Inc.) according to the manufacturer's instructions. To ensure uniform transfection efficiency in cells in the 96-well plate, transfection complex for each mutant was prepared in bulk quantities and incubated with the cells for 30 minutes (reverse transfection). The total mixture of cells and transfection complexes was then distributed into each well of the 96-well plate. The plates were incubated for 16 hours in a cell culture incubator (37° C., 5% CO₂, 100% relative humidity). Transfected cells were then treated with Compound 702 at different concentrations (0.5% DMSO) in duplicate for 7 hours. Cells were then lysed with 50 μl of iScript RT-qPCR Sample Preparation Reagent (Bio-Rad Laboratories, Inc). One step RT-PCR was performed using 2 μl of cell lysate and AGPATH-ID ONE-STEP RT-PCR (Life Technologies, Inc.) under the following PCR conditions: Step 1: 48° C. (15 min), Step 2: 95° C. (10 min), Step 3: 95° C. (30 sec), Step 4: 55° C. (30 sec), Step 5: 68° C. (1 min), then repeat Steps 3 to 5 for 35 cycles, then hold at 4° C. To amplify only transcripts derived from the transfected plasmids, PCR was performed with the SMN Forward A primer (GATGCTGATGCTTTGGGAAGT) which hybridizes to exon 6 of both SMN1 and SMN2 and a reverse primer that hybridizes to plasmid specific sequences. Minigene PCR products were separated on 4% agarose E-gels, stained with ethidium bromide and visualized using a gel imager (UVP).

Endpoint RT-PCR Analysis of Alternatively Spliced mRNAs in Cultured Cells

GM03813 cells derived from a patient with SMA type I (Coriell Institute) were plated at 5,000 cells/well in 200 μl DMEM with 10% FBS in 96-well plates, and incubated for 6 hours in a cell culture incubator (37° C., 5% CO₂, 100% relative humidity). Cells were then treated with Compound 702 at different concentrations (in 0.5% DMSO) in duplicate for 24 hours. After removal of the supernatant, cells were lysed in Cells-To-Ct lysis buffer (Life Technologies, Inc.). Reverse transcription was performed using 5 μl of cell lysate and the iScript RT enzyme kit (Bio-Rad Laboratories, Inc). PCR was performed using 5 μl of cDNA and Platinum Taq HiFi DNA Polymerase (Life Technologies, Inc.) under the following PCR conditions: Step 1: 94° C. (2 min), Step 2: 94° C. (30 sec), Step 3: 55° C. (30 sec), Step 4: 68° C. (1 min), then repeat Steps 2 to 4 for 33 cycles, then hold at 4° C. Alternatively spliced mRNAs were identified using primers listed in table 5. PCR products were separated on 2% agarose E-gels, stained with ethidium bromide and visualized using a gel imager (UVP).

Results

SMN1 mutant C6 (i.e., single substitution of original nucleotide T6 of exon 7 to C6) showed compound-dependent increased inclusion of exon 7, demonstrating that the C6/T is not the working site of the compound (FIG. 2A).

The initial work was focused on investigating the secondary structure of TSL2 (terminal stem loop 2, a predicted secondary structure in SMN2, not found in other responsive genes) as a potential working site of the compounds (FIG. 2B). Several mutations in that region were introduced to study the effect of the compounds on these mutants. One of the mutants particularly, SMN2 T43A, A51T (FIG. 3A), resulted in enhanced inclusion of exon 7 compare to wild-type SMN. However this mutant was resistant to compound-dependent inclusion of exon 7. No further enhancement of exon 7 inclusion could be achieved above baseline splicing in this mutant (FIG. 3B, 4A, 4B), and the effect appeared to be driven by A51 mutant, since the effect was more pronounced with A51T single nucleotide change mutant (FIG. 4A, 4B).

Additional mutants confirmed the functional role of a recognition element for splicing modifier (REMS) in SMN1 and SMN2 (FIG. 5A). The SMN2 G51, SMN2 C43G51 and SMN2 G43C51 mutants further demonstrated the functional role of A51, with decreased (G51, C43G51) inclusion of exon 7 compared to wild-type SMN2, (compare DMSO lanes), these mutants did not respond to compound (FIG. 5B). The SMN2 C53, SMN2 T53 and SMN2 G41C53 mutants further demonstrated the functional role of G53, with decreased (T53, G41C53) or increased (G41C53) inclusion of exon 7 compared to wild-type SMN2, (compare DMSO lanes), these mutants did not respond to compound (FIG. 5B).

In addition, the activity of the compound on splicing is maintained in mutations outside of the REMS (FIG. 6). The SMN2 A50T, SMN2 C44G50, SMN2 G44C50, SMN2 A44T50 mutants with either a decreased or an increased inclusion of exon 7 compared to wild-type SMN2, (compare DMSO lanes), showed compound-dependent increased inclusion of exon 7, demonstrating that position is not the interaction (direct or functional) site of the compound (FIG. 6).

Besides, testing the alternatively spliced mRNAs of additional genes also confirmed the existence of a consensus REMS. Testing results of alternatively spliced mRNAs are shown in Table 6 (affected genes), Table 7 (all genes tested) and FIG. 7 (correspond to Table 6), and are also summarized below:

For SMN2, the RT-PCR data showed that AGGAguaagu sequence motif resulted in a compound-dependent increase in the inclusion of exon 7 of SMN2 (increase from 40% to 100%.

For FOXM1, ATCAgtaagt sequence motif resulted in selectivity against the inclusion of exon 7A of FOXM1 in the presence of the compound. Only 10% increase in 7A inclusion was observed. However the upstream 5′ alternative splicing site within exon 7A of FOXM1 with the sequence motif of ATGAgtaagt (30 nucleotides downstream from the start of exon 7a) resulted in increased inclusion of exon 7A dC up to 90%.

For APLP2, ATGA sequence motif resulted in a compound-dependent increase in the inclusion of exon 7 of APLP2 (increase from 10% to 30%).

For GGCT, ATGA sequence motif resulted in a compound-dependent increase in the inclusion of exon 2 of GGCT (increase from 40% to 95%).

For ABHD10, ATGA sequence motif resulted in a compound-dependent increase in the inclusion of exon 5 of ABHD10 (increase from 10% to 30%).

For STRN3, AAGA sequence motif resulted in a compound-dependent increase in the inclusion of exon 8 of STRN3 (increase from 10% to 100%).

For VPS29, CAGA sequence motif resulted in a compound-dependent increase in the inclusion of exon 2 of VPS29. Notably this exon consist of only 12 nucleotides.

For ERGIC3, GAGA sequence motif resulted in a compound-dependent increase in the inclusion of exon 8 of ERGIC3 (increase from 0% to 10%).

For MADD, CAGA sequence motif resulted in a compound-dependent increase in the inclusion of exon 21 of MADD (increase from 0% to 5%).

For LARP7, CGGA sequence motif resulted in a compound-dependent increase in the inclusion of part of exon 1 of LARP7 (increase from 0% to 10%).

For LARP7, AAGA sequence motif resulted in a compound-dependent increase in the inclusion of exon 2 of LARP7 (increase from 5% to 40%).

For COL1A1, AAGA sequence motif result in a compound-dependent increase in the inclusion of exon 30 of COL1A1 (increase from 60% to 90%).
